Nibi Metrics
Real-time water levels, forecasts, and alerts for lakes and rivers across Canada and the US. Built on official government data.
Nibi Metrics turns raw gauge readings from official hydrometric networks into something a person standing on a dock can actually use: is the water high or low for today, which way is it moving, and how unusual is this? This page explains where every number on the platform comes from and what we do to it along the way.

About Sawmill C below U Tailrace near Sitka AK
Sawmill C below U Tailrace - a vital waterway near Sitka.
Sawmill Creek below U Tailrace is a noteworthy river experience situated near Sitka, Alaska. This natural feature plays a crucial role in the hydrology of Baranof Island, providing essential water resources to the surrounding ecosystem. The creek, measuring the changes in flow and elevation, flows silently beneath the rugged landscapes of the region, influenced by both seasonal dynamics and local weather patterns.
The watershed context
The Sawmill Creek watershed covers approximately 38 square miles, draining directly above the monitoring station. This catchment area contributes to the water levels in the creek throughout the year, particularly influenced by the subarctic hydrology that characterizes Alaska. Spring breakup and snowmelt are key drivers for annual flooding events, which may be complicated by ice jams. In contrast, glacier-fed rivers in nearby regions typically see their peaks in mid-to-late summer, while winter conditions tend to lower flow rates significantly as creeks remain under ice.
Sawmill Creek is accompanied by nearby waterways, including Indian River, helping to create a network of rivers that support both local flora and fauna and human activities in the area. While sitting at the confluence of multiple hydrological influences, Sawmill Creek provides vital water resources for ecological balance.
Why the data matters here
Today's reading from the Sawmill Creek below U Tailrace monitoring station is a useful indicator of current water conditions. The data sourced from the U.S. Geological Survey allows for comparison against the median for this calendar day, giving context to today's reading within the historical record. This particular gauge has been recording data consistently for over seven years, making its insights beneficial for understanding seasonal trends, predicting flooding risks, and managing the local ecosystem effectively. Monitoring programs like this help ensure that residents, anglers, and environmental stewards are informed about significant changes in water levels and flow, critical for maintaining the natural balance of this dynamic subarctic region.
How this page is built
Readings come from official government gauges and are rolled into daily records: the daily mean, high and low for every day on record. Each calendar day gets its own baseline from the full history, so the level you see is compared against what this specific date usually looks like rather than an annual average.
